NEW HAVEN, Conn., April 16, 2013 (GLOBE NEWSWIRE) --
Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today announced that it has initiated an international Phase 2 clinical trial with sovaprevir and ACH-3102 for the treatment of genotype 1 chronic hepatitis C (HCV). The trial will evaluate an all-oral 12-week interferon-free regimen consisting of sovaprevir, ACH-3102, and ribavirin in patients with chronic HCV who have not received prior therapy.
"With the initiation of this study, Achillion embarks on an aggressive and robust Phase 2 program. In previous clinical trials, both sovaprevir and ACH-3102 were shown to be efficacious, safe, well-tolerated, and had demonstrated a high barrier to resistance. Hence, we believe that a combination of these two agents for the treatment of chronic hepatitis C has the potential to be well-tolerated and provide high SVR rates," commented Milind Deshpande, Ph.D., President of Research and Development and Chief Scientific Officer of Achillion.
"Based upon the highly competitive SVR rates achieved to date with sovaprevir and the robust and unique single-agent activity observed with ACH-3102, our cornerstone NS5A inhibitor, we are optimistic about the results from this interferon-free trial," commented Michael Kishbauch, President and Chief Executive Officer of Achillion. "Achillion looks forward to reporting all-oral results from our ongoing clinical trials including RVR results from the -007 sovaprevir and ACH-3102 study during the third quarter of this year, as well as providing the updated SVR results later this month from our safety and tolerability study of ACH-3102 and ribavirin for the treatment of genotype 1b HCV."
Summary of Phase 2 '-007' Trial of Sovaprevir and ACH-3102
This is a Phase 2 trial which will evaluate the safety, tolerability and efficacy of 12 weeks of sovaprevir, ACH-3102 and ribavirin in up to 50 treatment-naïve patients with chronic genotype 1 HCV. Initially, 30 patients will be enrolled and randomized to receive either a combination of sovaprevir, ACH-3102 and ribavirin or matching placebos. Once daily 200 mg or 400 mg doses of sovaprevir with ACH-3102, given as a 150 mg loading dose followed by a 50 mg once daily dose, in combination with ribavirin, will be evaluated in this trial. Primary endpoints include safety, tolerability, and sustained virologic response 4 weeks after the completion of dosing (SVR4). The trial is expected to enroll patients at sites in the United States, Canada, New Zealand and Australia.
